Claims
exact text as granted — not AI-modified1. In an apparatus for dispensing a gas and a liquid from a container holding said gas and liquid, the improvement wherein the container includes a body having separate outlets for dispensing each of said gas and said liquid from said container, said outlet for said gas being in communication with the gas in the container and the outlet for the liquid being in communication with the liquid in the container, first valve means in said body associated with said outlet for dispensing said liquid and second valve means being associated with said outlet for dispensing said gas, means to open together each of said first and second valve means, wherein said body includes a conduit in communication with liquid in said container, said body having a chamber in communication with said conduit, said chamber having a conduit in communication with said liquid outlet, and wherein said separate outlets for said gas and said liquid are adapted to discharge separate gas and liquid streams from said body upon actuation of said means to open said first and second valve means.
2. The apparatus of claim 1 , wherein said body includes a transfer passage between said outlet for said gas and said second valve means for dispensing said gas.
3. The apparatus of claim 2 , wherein said transfer passage includes a bore perpendicular to said transfer passage, one end of said bore being connected to said transfer passage and the other end of said bore being in communication with the exterior of said body, and plug means for closing said bore at said other end.
4. The apparatus of claim 1 , wherein said outlets for dispensing said gas and said liquid are each connected to separate exterior conduits to convey separate streams of said liquid and said gas.
5. The apparatus as claimed in claim 1 , said first and said second valve means comprising an extended stem portion which is movable to open and close said outlets to dispense said gas and said liquid as separate streams.
6. The apparatus according to claim 1 , wherein said first and second valve means are connected to each other in operative association to simultaneously release said gas and said liquid as separate streams from said container.
7. The apparatus according to claim 1 , further including an elongate valve member, wherein said first valve means is formed at one end of said valve member, said second valve means formed at a position intermediate the other end of said valve member and said first valve means, said means for opening each of said first and second valve means positioned at the other end of said valve member.Join the waitlist — get patent alerts
